CONNECTOR FOR ELECTRICALLY-HEATED INSTRUMENTS.

Specification of Letters Patent.

Patented Feb. 1, 1916.

To all whom it may concern Be it known that we, FRANK KUHN and F RANKE.'SHAILOR,-CltlZBI1S of the United States of America, residing atDetroit, in the county of Wayne and State of Michigan, have inventedcertain new and useful Improvements in Connectors for Electrically-vHeated Instruments, of which the following.

is a specification, reference being had therein to the accompanyingdrawings.

The invention relates to conne tors designed for use on electricallyheate instruments such as sad irons and other movable tools.

The invention comprises the means employed for attaching said connectorandv for protecting the same mechanically and elec trically ashereinafter set forth.

In the drawings: Figure 1 is a.section "through a portion of anelectrically heated iron to which the connector is applied; Fig. 2 is ahorizontal section; Fig. 3 is a perspective view of one of the insulatorblocks; Fig. I is a perspective view sections of the housing; and Fig. 5is a perspective view of a .portion of the casing, with thecomplementary section of the housing connected thereto.

A is an. electrically heated instrumentsuch as a sad iron; B is theheating unit therefor; C are terminals secured to the unit B and proecting upward therefroi'n;

and D is an apertured casing through which the terminals-C project.

The flexible conductor E is secured to the terminal C by clamping screwsF or equivalent means for maintaining good electrical contact. Theterminals and adjacent portion of the conductor are then inclosed in aninsulator block' G which is provided with channels H forreceiving theterminals'and their clamping screws, and extensions of said channels Ifor receiving the adjacent portions of, the flexible conductor. channelsI are bent angularly to pass to one side of the bloclr G andtoproducethe necessary frictional resistance for preventing the transmission ofstrain to the terminals. 4

J is a handle for the instrument detachably engaging the housing D K isa housing for the blockG and which is formed in two sections K. and Khaving a clamping engagement with each other.

of one of the The The section K is attached to a portion of the handle Jand is provided with flanges K which embrace opposite sides of the blockThe section K has the flanges K for embracing the opposite sides of theblock G and these flanges have a snap clamping,

section K and the extension L so that mechanical stresses transmittedthrough the cord or flexible conductor will not be transmitted to theterminals but will be resisted by the housing K.

The construction is one which has the advantage of being easilyassembled, permitting the detachment. of the cord at any time for repairor for renewal while. at' all times, when the instrument is in use, ,aclamping engagement between the flexible conductor and terminal is.maintained, thereby preventing arcing.

IVhat We claim as'our invention is 1. In anelectri'cally heatedinstrument, the combination with a heating unit having a terminalprojecting therefrom, of a casing for inclosing-said unit apertured forthe passage of said terminal, a handle for said casing, a.flexibleconductor having a clam ing engagement with said terminal, an insulatorblock for embracing said terminal and adjacent portion of said flexibleconductor, a metallic housinghaving a section tary portion of saidhousing having a snap engagement with said attached section.

2. In an electrically heated instrument, the combination. with anelectrical heating unit, o f a terminal projecting therefrom. a casingfor inclosing said unit apertured for the passage of said terminal, ahandle forsaid casing, aflexible conductor having a clamping engagementwith said terminal, an insulator block channeled for the reception ofsaid terminal and having an extension angular channel for the passage ofsaid while the latter will secure the flexible conductor, ametallichousing sec I Lion secured to said h'andle and embracing Intestimpny whereof we'aifix our signaggyid i isu'ig'igtoi blbck, a guardfor said flexible I v tures in presence of tivd Witnesses/ en'nductor',mounted upon said housing sec f FRANK KUHNi elon. and\cbmplementary section for said FRANK E.
